Bug#314985: pmount: doesn't work with kernel 2.6.12

Bug#314985: pmount: doesn't work with kernel 2.6.12
Hello,
after some digging I think I found the problem in the function
sysfs_get_device_parent() of libsysfs1. If called by pmount it alway
returns NULL.
I think this is because it tries to get the parent by removing the
last part of the pathname. To make sure that it really gets a device
it checks for the presence of /detach_state. But there is no file
called detach_state in my entire /sys! Maybe this is somehow related
to http://lkml.org/lkml/2005/5/17/234 .
And here for reference the code libsysfs is executing
(sysfs_device.c:610):
| /*
| * All devices have the detach_state attribute - validate here
| */
| safestrcat(ppath, /detach_state);
| if ((sysfs_path_is_file(ppath)) != 0) {
| dprintf(Device at %s does not have a parent\n, dev-path);
| return NULL;
| }
